Naticln'in the county of Middlesex and State. 5of Massachusetts, have invented certain new` and useful improvements Yin Self-Feeding Disinfecting Vand Deodorizing Devices,y of Y' l a, h

. vided with rearwardly 'extending pro] ect'l'on'sv which the following is a specication. y

This invention relatesto improvements 1n clevices,jand it consists essentially in the construction, arrangement, *and combination ofthe several'parts of ithe` fdevice, as 'willbe hereinafter fully described, and briefly set fffortli inthe claim.v v

r)lie .principal objects ofthe invention are to provide a reliablef ancleconomical 'selffeeding, disinfectingand deodorizing device, ,l

anda cage or "casing for yholding the same to prevent` 1t being intentionally, or.otherw1se, removed from its support. v

Other objects of thev invention will become apparent in the detail description of. the

In the drawings-Figure 1 isa front elevation of my improved fself-feedingv disinfecting and deodorizing device, secured to a suitable support, and having the lowerportion of the sliding hood Vor cover broken away. Fig. 2 is a vertical longitudinall ceny tral section ofthe device, showing the Vsliding hood or -cover in position, and locked, and the disinfectant Y holder andl gas-,generator in position. Fig. 3 is a horizontal cross* section, taken on the line 3-3 Fig. 2. Fig.

4 is asimilar view taken on the line 4 4 Fig. 2. Fig. 5 is a horizontal cross-section, looking upward, taken on line 5-5 Fig. 2, and Fig. ,6 is a detail view, enlarged, of the 40 bottomportion of the hood or cover, looking from the rear thereof. l

Referring to the drawings, the numeral 1 indicates the cage or casing of my self-feeding disinfecting and deodorizing device,'and

2a suitable'support, Vto which it isto be secured when placed in position for use. This cage or casing is, preferably made in two parts, 3 and 4, the back and bottom, re-

n spectively, and 5 a sliding hood or cover, preferably curved incross-section, as shown, and provided with a suitable top portion 6,

' either flat, or ofy any other approved construction. The back portion 3 and the bottom portion 4` are preferably formed from a single piece of sheet metal by means of suitable dies. The back portionl 3 isvpro- AYself-,feeding disinfecting andV deo'dorizing i Speci'caton of Letters Patent. Patented @(513,19, Appliea'tibh'alea December 5,1913.

Thehood ro'rfcfover of the lcage orcasing`y consists of thecurved wall 5 and the top f portiony 6', vand tothe under V-side of this, top

portion"' 6 is securedV a suitable lock 14, adapted, when the hood vor coveriis in position, to

engagethe portion 9 ofthe edge 8, for the purposey Vof lockingV saidfl hood or cover Y against displacement, or removal,` and there- `by preventing accessjto the'interior of saidA .cage or casing without theikey, either for the purpose -of removing thev contents `thereof, or for removing sa1dcage,or casing, from its support. vThe cage or casing is secured to the support-,2 by suitable securing means, preferably screws, or bolts, eXtend- Vlng from the inside of the cage ,or casing,

through theback portion 3 intosaid supremoved from said support eXcept when said cage ori casing is open. The rear portionof said hood or cover `is provided with inare so cut-away 17 for a purpose hereinafter stated.

` The numeralilS indicates a tubular shaped vaporizer, of ,suitable height. and thickness, v

adapted to be seated in the drip orfeeding."

pan 12 aroundthe raised` or embossed lporf tion 12', as shown in Fig j4. rlhis vaporizer is made-from asuitable'porous material, preferably'unglazed terracotta'. i .Y f

19 indicates the holder-or reservoir for l' thev disinfecting andjdeodorizing fluid, and

port, wherebysaid cage or casing' cannot be "5f Y is located within said casing above saidl vaporizer, with the contracted open end thereof setting into the opening in said vaporizer and resting on the embossed or raised portion 12 of the drip or feeding pan 12, as is apparent. c

20 indicates an adjustable strap secured to the lugs or ears 13, 13, and is for the purpose of holding the reservoir 19 in proper position, as is evident.

rlhe operation of the device is as follows: The pan 12 being placed in its seat in the bottom portion 4f, the vaporizer is set therein, and the reservoir,flled with the fluid, set in properY position over said vaporizer and under said adjustable strap 20, when the lower contracted open vend of said reservoir will project through the opening in said vaporizer and rest upon the embossedv portion 12lv of the pan 12. When thus arranged the fluid will feed down from the lreservoir inta thek feeding pan 12, and be absorbed by the porous vaporizer 18, and passed o there-v from, by evaporation, in the form of vapor', which passes out'through suitable openings in the cage or casinginto the space to be disinfected or deodorized.V When the reservoir is in position the'hood or cover is placed over the back portion 3, the flanges 15, 15,'

sliding downward back of the flanged edges 7, 7 the ange `16 back of the flange 8,V and the prongs 17, 17,'over the rearwardly eX- tending projections 10, 10, and the bolt of the lock 14 shot beneath the portion 9 of the flange 8, when the device will be locked.

Having thus fully described my invention 1 claim y In a disinfecting device, a casing comprising a back plate having odset side flanges, rearwardly extending projections on said flanges adjacent their lower ends, a bottom plate extending forwardly from said back plate, a hood disposed outwardly of said bottom plate and having inwardly eX- tending side flanges slidablyy engaging the rear faces of said first named flanges, said last named flanges being cut away adjacent their lower ends to form prongs engaging over said projections for preventing downward movement of said hood, an inwardly extending projection on'the top of said back plate, a flanged cover. plate seated upon the top edges of said back plate and hood, and means carried by saidcover plate and engaging beneath said last named projection.

` ln testimony whereof I alhX my signature in presence of two witnesses.
